Application filed September 15, 1923. Serial No. 662,895.

To all whom it may concern; I Be it known that I, J osnrrr MoMoNAeLn, a citizen of the United States, residing at Cleveland Heights, in the county of Guya- 5' hoga and State of Ohio have invented certain new and useful Improvements in Lasts, of which the following is a specification.

This invention relates to improvements in adjustable lasts, having for-an object to prol vide a last including a minimum number of parts and having awide range of adjustment. 1

Another object is to provide a last of this character in which the heel and sole portions may be independently adjusted and in which the adjusting means is extremely simple and reliable.

It is likewise an object to provide a last including a wedge block arranged upon the upper face of the sole portion, said block being removableto permit adjustment of the sole portion and to permit use of the last exclusive of said block as is often desired.

Other objects willbe in part obvious and in part pointed out hereinafter.

In order that the invention and its mode of operation may be readily understood by persons skilled in the art, I have in the accompanying drawings and in the detailed 30 following descriptions based thereon, set out one possible embodiment of the same.

In these drawings Fig. 1 is a side elevation of the last;

Fig. 2 is a bottom plan view thereof;

Fig. 3 is a section taken on the line 33 of Fig. 1;

Fig. 4 is a Vertical longitudinal section;

Fig. 5 is a side elevation showing a superposed wedge block in position;

Fig. 6 is a section taken on the line 66 of Fig. 5; and

Fig. 7 is a detail of the screw operating lever and reversible pawl.

Having more particular reference to the drawings throughout which similar characters of reference will designate similar parts, the last may be broadly stated as comprising an intermediate or body portion 8, carrying on one side an' adjustable heel portion 9, at its other side a laterally expansible sole por tion 10 and when desired a longitudinally adjustable wedge block 11 arranged upon the upper face of the sole portion.

The intermediate or body portion 8, is pro- Vided in its lower face with a longitudinal under out way or channel 19; which is adapted to receive a shouldered upstanding lug or head 13 carried by the extension 14 of the heel portion 9. As shown this lug is thread-' edly engaged with a rotary screw 1 one end of which is disposed in a depending lug 15 formed in the channel 12 as indicated in Fig. e. The outer end of the screw 1 carries a reversible pawl and ratchet mechanism 16 whereby the screw may be rotated 05 and consequently adjust the heel portion longitudinally.

The sole portion 10 consists of two coacting parts preferably hollow, and having at their rear ends attaching lugs or cars T0 17, notched as shown for engagement with pivot or hinge pins 18 carried by the body portion as indicated in Figs. 1 and 2. The two sections are cut away as at 19 to permit positioning and manipulation of a reversible pawl and ratchet mechanism 20 by means of which a rotary screw 21 is operated. This screw as shown is mounted in a socket formed in the forward face of the body portion 8 in which is arranged a cross pin to retain the headed end 22 of the screw in proper position.

A wedge 23 is movable-upon and with rotation of the said screw 21 and is engageable with a pair of spaced vertical pins 24 arranged in the sole portion and upon forward movements of the wedge it is obvious that the hinged parts of the sole portion will expand laterally. As indicated in Fig. 2, the forward lower faces of the sole portion are over-lapped to provide a smooth surface.

In order that the sole portion may be retained against expansion, a hook 25 is car-- ried by one section and engageable with a pin 25 on the other section as shown in Fig. 2.

Often times it is essential that an addi tional block be inserted in the position I have indicated inFig. 5 wherefore 1 provide the substantially wedge shaped block 1.1 movable along the upper surface of the sole portion under influence of a rotary screw 27 which is mounted in a socket 28 in the same manner as the preceding screw. 193 The last named screw 27 is also removable so as to permit manipulationv of the main screw 21. The removable feature also provides for use of the last without the wedge block 26, as is often desired. A pawl and 119 ratchet mechanism 29 is arranged upon the last named screu 27 for reasons which are apparent.

At times the expansion of the sole portion is unnecessary and at such times the.

two-sections may be secured together and the ad usting screw removed.

The lnterniediate or body portion 8 is provided with a socket 30 whereby mountscope of my claims, I consider within the spirit of my invention.

I claim:

1. An adjustable last, comprising an independent body portion having an undercut way formed longitudinally of its lower face, a screw arranged in the way and carried by the portion, a heel portion, an upstanding lug carried by the heel portion and movable lon itudinally and guided within said way with rotation of the screw whereby to lengthen the last, and a sole portion carried by the body portion.

2. An adjustable last, comprising an independent body portion having an undercut way formed longitudinally of its lower face, a screw arranged in the way, a heel portion, an upstanding lug carried by the heel portion and movable longitudinally and guided within said way with rotation of the screw whereby to lengthen the last, an expansible sole portion arranged upon the body ortion.

3. n adjustable last, comprising a body portion, a heel portion carried by said body portion, a two-part sole portion hinged to the body portion, a screw carried by the body portion and a wedge movable longitudinally with rotation of the screw and adapted to laterally expand the sole portion, and a wedge arranged upon the sole portion and adjustable to vertically expand the instep portion of the last independently of the remaining portions of the last.

at. An adjustable last, comprising an independent body'portion, a pair of forwardly extending co-acting sole, portions pivotally connected to the forward end ofv the. body portion, a pair of depending, spaced. pins carried by the sole portions,"a rearwardly extending heel portion slidablyarranged in the body portion, a pair of screws, one of said screws being adapted to, adjustthe heel portion, and means carried by the second screw for laterally expanding the sole portion, said means comprising a wedge' movable with rotation ofthe screw and acting upon the pins. r

An adjustable last, comprising an independent body portion having a longitudinal under-cut way in its lower face, a pair of forwardly extending co-acting sole portions pivotally connected to the-body portion, a rearwardly extending heel portion having a headed lug slidably arranged in the under-cut way in the body portion, a pair of screws one of said screws-being adapted to adjust the heel portion, a wedge carried by the second screw for expanding the two-part sole portion and a wedge block longitudinally adjustable upon the upper face of the sole portion.

In testimony whereof, l mysignature. 1
